Crossing border into Port Huron , Michigan with tanker

Hey just wondering what paperwork, i will need in order to correctly cross into the USA , Port Huron entry with a non hazardous tanker empty ?

Im just a regular tanker trucking company working only in Ontario currently, and I will have to cross into the US soon with a new job, i'l be getting. I haul calcium chloride liquid salt brine.

Last contained paper or washout ticket while crossing empty into USA ? Any help is much appreciated.

We'l be loading salt brine in Michigan and bringing back across to Canada, and only part of that I know for sure is using my customs broker to properly clear load ahead of time.

thanks in advance
